Imidazolinone Herbicide Effects on Rotational Crops Following Peanut (Arachis hypogaea L.) in South Texas

Abstract

The effect of imazapic and imazethapyr on crops that may be rotated with peanut were studied in the field at three south Texas locations. Corn, cotton, grain sorghum, watermelon, potato, and sesame were planted the year following imazapic and imazethapyr POST application to peanut. Plant dry matter weights indicated cotton was most sensitive to a rotational program with imazapic in peanut. Dry matter weights with other crops were variable.
